Swan Lake is a permanent freshwater lake located within the Discovery Bay Coastal Park on Phillip Island, Victoria. It is a quiet, serene oasis surrounded by protected wetland habitats. The lake's shores are fringed with paperbark trees, and a gentle walking trail circuits its perimeter. For paddlers, the overall character is one of calm and natural observation. A boardwalk provides good access to the lake, which could serve as a potential put-in point, though specific launch facilities for boats are not detailed. The lake is part of a coastal park, and paddlers should be aware that off-road vehicle access in the broader park area is currently paused, which may affect how you transport your craft to the water's edge. The area is a haven for wildlife, particularly birdlife, with viewing hides accessible via the boardwalk, making it an excellent location for quiet, non-motorized paddling to observe wetland species. The trail around the lake is suitable for walking, indicating that the surrounding terrain is gentle. No specific hazards, water quality issues, seasonal restrictions, or recommended paddling routes are mentioned, so paddlers should plan conservatively, assume typical freshwater lake conditions, and check with Parks Victoria for any specific boating regulations before a visit. The lake's setting within a coastal park suggests a protected, natural environment focused on conservation.
